WTF is it?!? Round 7

Since people haven't been able to properly name our WTF is it?!? item for a few weeks now, I thought we would go with a food item nearly guaranteed to be identified. I mean, this one is easy. Too easy.

So for clarity's sake, the egg is in the pic for scale. And here's an additional hint: It's in season now. The object in question is bright yellow, as you can see, and resembles a melon or gourd. Which is it? I dunno. You tell me.
